About this event
Speaker: Zeinab El-Sayegh, PhD, PEng, Department of Automotive and Mechatronics Engineering, Ontario Tech University
This session will introduce the concept of virtual soil moisturization and its impact on the performance of 315/80R22.5-sized truck tires. The truck tires are simulated using multiple layers and materials in a Finite Element Analysis (FEA) environment. Moist sand, composed of layered water and sand particles, is simulated using the Smoothed-Particle Hydrodynamics (SPH) technique. The numerical interaction between sand and water is determined using Darcy’s law. The tire-sand interaction is defined by a hybrid FEA-SPH interaction model, and the tire's tractive performance—including tractive effort, motion resistance coefficient, and tire sinkage—will be presented. Finally, the challenges of validating such models will be discussed, along with future work on developing more advanced tire-terrain models.
ISTVS has been hosting online events for research on terramechanics and terrain-vehicle systems under our Digital Event Series since 2021. Recordings from the series are posted to our YouTube channel. Make sure you’re subscribed to the ISTVS Newswire to keep up on upcoming events.

George MasonG
Dr. George Mason worked for 33 years as a research engineer in the Mobility Systems Branch, Engineering Systems and Materials Division, Geotechnical and Structures Laboratory, as the Army’s lead researcher for studies on vehicle mobility. Later, he joined the Center for Advanced Vehicle Systems (CAVS) at Mississippi State University as a Research Civil Engineer. His work in mobility research was related to military areas, encompassing geospatial analyses, discrete element modeling of soils, and investigating vehicle/terrain interaction. The research required the application of advanced theories of soil physics and soil mechanics to quantify complex physical phenomena associated with the science and engineering of off-road vehicle mobility and the study of changes in associated surface geology.
